Tootsie Roll In 1896, the Tootsie Roll was introduced by Austrian immigrant Leo Hirshfield to the U.S. In a small store in New York City, he began producing his a chocolaty, chewy candy, which he named after a nickname of "Tootsie" for his five-year-old daughter, Clara. He was America's first candy maker to individually wrap penny candy. By 1905, production moved to a four-story factory in New York. During World War II, Tootsie Rolls were added to American soldiers' rations because of their ability to withstand severe weather conditions and give quick energy. Tootsie Rolls are made from a base of sugar, corn syrup, soy-bean oil, skim milk and cocoa. Current production is over 49 million pieces a day. |

birth Philip Showalter Hench Born 28 Feb 1896; died 30 Mar 1965 at age 69. American physician who was one of the leaders in American rheumatology. He shared the Nobel Prize for Physiology or Medicine in 1950 for discoveries relating to the hormones of the adrenal cortex, their structure and biological effects (with Edward C. Kendall and Tadeus Reichstein of Switzerland). In 1948, Hench was working at the Mayo Clinic, Rochester, Minnesota. He noticed that during pregnancy and in the presence of jaundice the severe pain of arthritis may decrease and even disappear. With Kendall, he successfully applied an adrenal hormone (later known as cortisone) in the treatment of rheumatoid arthritis. |

birth Pavel Sergeevich Aleksandrov Born 25 Apr 1896; died 16 Nov 1982 at age 86. Soviet mathematician who made important contributions to the field of topology (the study of related physical or abstract elements that remain unchanged under certain distortions) and one of the founders of the theory of compact and bicompact spaces. Aleksandrov introduced many of the basic concepts of topology, such as the notion that an arbitrarily general topological space can be approximated to an arbitrary degree of accuracy by simple geometric figures such as polyhedrons. Giving support to international cooperation, he supervised the publication of an English-Russian dictionary of mathematical terminology (1962). |

![]() Gabriel-Auguste Daubrée |
death Gabriel-Auguste Daubrée Died 29 May 1896 at age 81 (born 25 Jun 1814). French geochemist and a pioneer in the application of experimental methods to the study of diverse geologic phenomena. His appointment as professor of geology and mineralogy at Strasburg furnished him with a laboratory suitable for his experimental work in synthetic geology, begun in 1849. He studied the artificial production of minerals, the geological action of superheated aqueous vapour, the effect of mutual abrasion, the influence of pressure and strain in mountain-making, etc. During the years 1857-61 he made a detailed study of the hot springs of Plombières, observing at the same time the chemical action of thermal waters. Daubréelite (CrS), a grayish granular mineral found in meteoric iron, was named after him. |

![]() August Kekulé |
death August Kekulé Died 13 Jul 1896 at age 66 (born 7 Sep 1829). Friedrich August Kekulé von Stradonitz was a German chemist who devised the ring structure of carbon atoms in organic molecules. Although at first intending to study as an architect, his career in chemistry began after hearing Justus Liebig's lectures. He determined the tetravalence of carbon, and its ability to link in chains and form polyvalent radicals (1857-58). Further, he envisioned double or even triple bonds between carbon atoms in those chains, and isomers being molecules with the same atoms arranged differently. From a vision of a serpent catching its own tail, Kekulé realized that benzene has a ring structure (1863). Kekulé's ideas became the foundation of structural theory in organic chemistry. |

death Otto Lilienthal Died 10 Aug 1896 at age 48 (born 23 May 1848). German aeronautical engineer and inventor whose pioneering studies formed a foundation for Octave Chanute and the brothers Wilbur and Orville Wright. His prior inventions, such as a small steam engine that worked on a system of tubular boilers designed for safety, brought him financial success. In 1891, he built and flew in the Derwitzer Glider. Within the next five years (before he died in a crash), assisted by his brother, Gustav, he designed other gliders and made 2000 flights. He carefully studied the aerodynamics of rigid wings, inspired by the gliding flight of storks made without flapping their wings. Although his aircraft achieved only low speed and altitudes, and he had survived other crashes, he broke his spine and died the day following a crash, falling from about 56-feet. |

birth Sheldon Glueck Born 15 Aug 1896; died 10 Mar 1980 at age 83. Sol Sheldon Glueck and his wife Eleanor were an American criminologists and researchers at Harvard Law School, a husband-and-wife team whose numerous studies of criminal behaviour and of the results of correctional treatment profoundly influenced criminal justice, both legislatively and administratively. In 1940 the Gluecks began work on their best-known study, Unraveling Juvenile Delinquency (1950). This ten-year project addressed the development of criminal careers and involved a detailed examination of 500 delinquents and 500 nondelinquents from disadvantaged neighborhoods in the Boston area. Then, for the next fifteen years, the Gluecks conducted an extensive follow-up of the original sample. |

They decided upon careers in medical research, took positions in America in 1922, and became U.S. citizens in 1928. They both shared the 1947 Nobel Prize in Physiology or Medicine (with Bernardo Houssay). The Coris were recognized "for their discovery of the course of the catalytic conversion of glycogen." After Marie Curie and Irène Joliot-Curie, Gerty was the female Nobelist in science. |

birth Carl Cori Born 5 Dec 1896; died 20 Oct 1984 at age 87.

Their discoveries earned them (with Bernardo Houssay) the Nobel Prize for Medicine or Physiology in 1947. |

![]() Ernst Engel |
death Ernst Engel Died 8 Dec 1896 at age 75 (born 26 Mar 1821). German statistician, the head of the Prussian Statistical Bureau (1860-82), known for the "Engel curve," or Engel's law, which states that the proportion of expenditure on food will fall as income rises, i.e. food is a necessary good. Engel's law applies to goods as a whole. Demand for food, clothing and shelter - and for most manufactured products - doesn't keep pace with increases in incomes. Engel curves are useful for separating the effect of income on demand from the effects of changes in relative prices. Engel also examined the relationship between the size of the Prussian rye harvest and the average price of rye over a number of years prior to 1860, probably the first empirical study of the relationship between price and supply. |

![]() Radio demonstration |
Radio demonstration In 1896, Guglielmo Marconi gave the first public demonstration of his radio equipment at Toynbee Hall, East London. He was introduced by William Preece, chief electrician of the British Post Office. Preece saw the value of wireless telegraphy to replace the existing post office wire service. The use of the hall had been arranged by Preece, who advertised the event, drawing a considerable audience, and the press. While Marconi tapped the key on the transmitter, Preece carried the receiver box around the room showing that there were no wires yet a bell in the receiver rang each time Marconi closed the key. Through his mother's British society connections, Marconi had met Preece and benefitted from his patronage. |
